The pruritic dermatoses

Systemic diseases that produce itching are listed in Table 1. Control of prurtis in each case depends on control of the fundamental disease. Intolerable itching may require the combined services of a generalist, a dermatologist, an internist or subspecialist. Prurtis is a common symptom, not completely understood, mediated by stimulation of nerve endings in the skin. It may be produced by internal or external stimuli, may be mild or severe, and its cause is often obscure. Treat the symptoms and watch for developments.
